One platform to test
everything. At any scale.
Your Systems Don't Fail in Isolation. They Fail End to End. Stratos™ tests the entire workflow — across every system, every handoff, every dependency — at production scale, in one governed platform.
Platform Overview
What is the Stratos™ platform?
Stratos™ is Clear Sky's AI-powered enterprise test automation platform that validates complete business workflows end to end — across UIs, APIs, batch jobs, and EDI workflows — at production scale in one governed platform.
It matches dedicated UI and API testing tools on the fundamentals — including simple, standalone, cross-browser web UI tests and lightweight API checks — and then adds the batch and EDI, connected-system, and system-of-systems layers those point tools can't reach. It runs complete functional user journeys under production-scale load — simulating up to 25,000 concurrent virtual users across 43+ geographic regions — and covers functional, performance, API, batch and EDI, regression, and compliance testing with both no-code and code-based automation.
Platform Capabilities
Built for the complexity your
enterprise actually faces
Seven capability areas — one integrated system. Stratos™ replaces the patchwork so your teams can focus on shipping with confidence.
AI-Powered Test Intelligence
Stratos uses governed AI to help users create stronger test coverage faster — without replacing human review or control.
- Requirements-to-Test Generation — Convert requirement documents, spreadsheets, user stories, and workflow descriptions into structured test scenarios. Accelerates requirements as test cases while preserving user review and approval.
- Scenario Generation & Coverage Expansion — Generate positive paths, negative tests, edge cases, and workflow variations. Creates scenarios test engineers may miss when writing manually.
- AI-Assisted Test Refinement — Improves clarity, completeness, and structure of generated scenarios.
- Human-Reviewed AI Output — Users review, edit, approve, or reject scenarios before execution.
End-to-End Workflow Validation
Stratos validates complete enterprise workflows across systems, not isolated test steps.
- Cross-System Workflow Orchestration — Validate business processes that span full end-to-end applications. Reduce blind spots created by fragmented toolchains.
- UI, API, and Batch Flow Coverage — Combine front-end interactions, service calls, and asynchronous processing into unified test scenarios. Validate asynchronous end-to-end flows that begin with incoming batch files, trigger downstream processing across systems, and produce outgoing files or business outcomes that can be verified after completion.
- System-of-Systems Testing — Test how systems-of-systems behave together, not just whether individual components respond. Model real enterprise architectures where failures occur between platforms, teams, and integration points.
Flexible No-Code and Code-Based Automation
Stratos gives teams the flexibility to build automation the way each workflow requires — using no-code speed, code-based control, or both together in the same platform.
- No-Code Record and Playback — Create automated UI workflows quickly by recording user actions and turning them into repeatable tests. Use synthetic data in UI workflows to introduce input variability and simulate more realistic testing conditions.
- Code-Based Automation for Complex Scenarios — Build deeper automation for advanced, high-complexity, or highly customized testing requirements. Use code when workflows require greater control, custom logic, complex assertions, or specialized handling.
- Test-by-Test Migration from No-Code to Code — Start with no-code automation, then generate code from the recorded test when deeper customization is needed. Mix and match no-code and code-based tests across the same suite, or start from empty code for fully custom automation needs.
Batch and Asynchronous Workflow Testing
Stratos handles everyday UI and API testing as well as any dedicated tool — and adds the layer they skip. Mainstream test tools ignore the asynchronous backbone of enterprise systems, so Stratos provides first-class orchestration for batch workflows — the hardest-to-test, highest-risk layer of your stack.
- Batch Process Validation — Test scheduled, file-driven, and asynchronous business processes. Validate outcomes after downstream processing, not just initial job execution.
- Synthetic Batch File Generation — Generate tens of thousands of synthetic data rows that conform to customer-defined file specifications, layouts, and business rules. Create realistic batch inputs for high-volume workflow testing without relying on sensitive production data.
Functional and Performance Testing in One Platform
Test the way your system actually behaves in production — not just under idealized conditions. Stratos validates complete user journeys under realistic load.
- Journeys Under Load — Execute full functional workflows under production-scale load. Go beyond 'the system is fast' to prove business logic holds under pressure.
- Concurrent Virtual User Execution — Simulate high-volume traffic across key workflows. Test system behavior under realistic concurrency and load conditions.
- Global Execution Reach — Run tests from distributed locations to evaluate real-world user and system behavior. Identify geography-sensitive latency, throughput, and availability issues.
Unified Execution and Reporting
Stratos consolidates fragmented testing activity into one execution and visibility layer.
- Single Execution Platform — Organize test scenarios into features, test suites, and test plans for optimum efficiency. Reduce tool sprawl and coordination overhead.
- Centralized Test Results — Bring execution outcomes into one reporting experience. Give teams a clearer view of what passed, what failed, and what requires attention.
- Evidence-Ready Reporting — Capture test results, execution details, and supporting artifacts. Help teams document what was validated and under what conditions.
Protocol and Integration Testing
Stratos combines no-code speed with code-based flexibility so teams can validate complex integrations, custom protocols, and system-to-system workflows that go beyond standard UI and API testing.
- Multi-Protocol Validation — Use no-code automation where workflows are straightforward, and code-based automation where protocols, payloads, or system behaviors require deeper control. Test across APIs, custom protocols, raw socket connections, batch interfaces, and connected-system communication patterns.
- Integration-Point Coverage — Validate the seams between systems where production failures often occur, including handoffs, dependencies, file exchanges, and downstream processing. Mix no-code and code-based tests to cover both business-facing workflows and deeper technical integration paths.
- Legacy and Modern System Support — Validate workflows across cloud-native services, legacy systems, packaged platforms, custom applications, and specialized enterprise interfaces. Support real enterprise environments where workflows span multiple technologies, protocols, and integration patterns.
Why Stratos™
Competitive Comparison
Most testing platforms are optimized for one layer of the quality problem. Stratos matches dedicated UI and API tools on the fundamentals — including simple, standalone, cross-browser web UI tests — and then adds the layers they can't reach: backend systems, batch jobs, EDI, connected systems, and production-like load. You get everyday UI and API testing and complete system-of-systems validation in one platform, with traceable evidence for every release.
